Kingston DC1500M ane.92TB Data Heart Enterprise SSD Review
Kingston's newest enterprise SSD, the DC1500M, is designed for a broad range of datacenter applications. Bring together us as we test information technology.
Rating: 93% Manufacturer: Kingston (SEDC1500M/1920G)
Introduction and Drive Details
Kingston Digital is now shipping the DC1500M enterprise SSD for datacenter applications. The DC1500M supports up to 64 namespaces, making it platonic for virtualized environments and applications such as web hosting. The drive has at its heart a Silicon Motion Inc. 16-channel SM2270 controller. SMI'due south SM2270 controller has congenital a well-deserved reputation for delivering consistent, predictable performance nether a broad range of datacenter workloads.
For flash, Kingston is using BiCS4 96Layer TLC. We like this selection as it has proven to deliver random read performance superior to other 96Layer flash choices. A sixteen-channel Silicon Motility SM2270 controller managing a BiCS4 flash array should be a recipe for high QoS (Quality of Service), which is exactly what Kingston is claiming the DC1500M is all near. Let'southward go Kingston'due south newest datacenter SSD on the bench and run across if the results match the claims.
Quick Specs/Comparison Products

Current online pricing finds the 1.92TB DC1500M retailing for approximately $484.
Enterprise Testing Methodology
TweakTown strictly adheres to industry-accepted Enterprise Solid State Storage testing procedures. Each test we perform repeats the same sequence of the following four steps:
- Secure Erase SSD
- Write entire capacity of SSD a minimum of 2x with 128KB sequential write information, seamlessly transition to next step
- Precondition SSD at maximum QD measured (QD32 for SATA, QD256 for PCIe) with the test specific workload for a sufficient amount of time to achieve a constant steady-state, seamlessly transition to next stride
- Run test specific workload for 5-minutes at each measured Queue Depth, record results
Benchmarks - Random and Sequential Performance
4K Random Write/Read
Nosotros precondition the drive for 16,000 seconds, receiving performance information every 2d. Nosotros plot this information to find the test subject'due south descent into steady-state.
Steady-state is accomplished at 6,000 seconds of preconditioning. The boilerplate steady-state write operation at QD256 is approximately 240K IOPS. The relatively tight design with about no outliers indicates a high QoS.
Nosotros have no problem sustaining 240,000 4K random write IOPS which is 20K meliorate than Kingston's stated sustained random write spec. Kingston's newest delivers the 2nd highest write operation for any flash-based SSD we've tested to engagement. When we gene in its outstanding low queue depth functioning, we are of the opinion that the DC1500M delivers the best-in-form 4K random write functioning. Outstanding
Kingston specs the DC1500M 1.92TB for up to 510,000 random read IOPS, and once more we exceed manufactory specs by roughly 20K IOPS. Overall, the DC1500M is delivering average 4K random read performance.
8K Random Write/Read
We precondition the drive for 16,000 seconds, receiving operation information every second. We plot this data to observe the test subject field's descent into steady-state.
Steady-state is achieved at 7,000 seconds of preconditioning. The average steady-state write performance at QD256 is approximately 112K IOPS.
We wait 8K random to rail exactly the same equally 4K random, just at a 50% lower rate. This is exactly what we get. Again, nosotros will point out the DC1500M is delivering the best performance where it matters the about, QD1, for whatsoever flash-based Gen3 SSD we've tested. Splendid.
Hither we wait to see our chart tracking the same as our 4K chart with somewhat lower functioning. Results come in better than expected, as nosotros find the DC1500M delivering better than average operation at QD1-QD32. Overnice.
128K Sequential Write/Read
We precondition the drive for 6,500 seconds, receiving performance data every second. Steady-state for this exam was already accomplished when we filled the drive with 128K seq data. A whole string of outliers going in the wrong direction indicates poor QoS when writing data sequentially.
The boilerplate steady-state sequential write performance at QD256 is approximately 2,200 MB/s.
Our testing indicates mill sequential write specifications to exist overstated past almost 500 MB/s. However, when we step back and look at its performance at QD4 and QD8, we detect it's the best nosotros've seen from a 2TB class PCIe Gen3 enterprise SSD to appointment. We call up that the factory specs of ii,700 MB/southward for the i.92TB model might be a typo.
It looks like the DC1500M is trying to make upwards for underperforming vs. stated sequential write spec by exceeding stated spec by roughly 400 MB/s when reading sequential data. That's a nice trade-off that we will gladly accept any solar day as read functioning is more important than write for the bulk of applications. Additionally, and worth noting is the fact that at QD8-xvi, the DC1500M is the best we've tested.
Benchmarks - Server Workloads
Email Server
An Email Server workload is a enervating 8K test with a 50 pct R/Due west distribution. This application gives a good indication of how well a drive will perform in a write-heavy workload environment.
We precondition the drive for sixteen,000 seconds, receiving functioning data every second. We plot this data to detect the test subject's descent into steady-state.
Steady-State is achieved at approximately 14,000 seconds of preconditioning. The average steady-state workload performance at QD256 is approximately 90K IOPS.
The small number of outliers indicates boilerplate to above average QoS.
The typical operating region for most enterprise workloads is in the QD1-QD16 range. The DC1500M delivers the best Gen3 operation we've seen here at QD1-viii. This is where we desire to encounter infrequent performance, and this is right where the DC1500M is serving it up in a large fashion.
OLTP/Database Server
An Online Transaction Processing (OLTP) / Database workload is a demanding 8K test with a 66/33 percent R/W distribution. OLTP is the online processing of financial transactions and loftier-frequency trading.
We precondition the bulldoze for xvi,000 seconds, receiving performance data every second. Nosotros plot this information to observe the test subject's descent into steady-land.
Steady-state is accomplished at fifteen,000 seconds of preconditioning. The average steady-country workload performance at QD256 is approximately 112K IOPS.
The pocket-sized number of outliers indicates boilerplate to higher up average QoS.
Over again, the DC1500M shows us all-time in form performance at low queue depths. Functioning that matters.
Web Server
A Web Server workload is a pure random read test with a wide range of file sizes, ranging from 512B to 512KB at varying percentage rates per file size.
We precondition the bulldoze for 16,000 seconds, receiving performance information every second. We plot this data to observe the test discipline's descent into steady-state.
We precondition for this exam with an inverted (all-write) workload, and so no relevant information tin be gleaned from this chart.
More practiced stuff from the DC1500M. Nosotros observe information technology is essentially tied with the DC-P4510 for the best Gen3 performance at queue depths upwardly to eight.
Concluding Thoughts
Kingston's DC1500M displayed its prowess over a broad range of datacenter use instance scenarios we tested information technology against today. The drive impressed with its low queue depth performance and demonstrated that information technology is a force to be reconned with as it delivered some of the best PCIe Gen3 sustained performances nosotros've seen to date.
The DC1500M 1.92TB impressed us across the lath, with the lone exception of not delivering sequential write performance that matches stated performance. This isn't a big deal because it is delivering exactly as expected for a 2TB class PCIe Gen3 datacenter SSD, maybe even a piddling improve.
Kingston's newest datacenter SSD delivered performance where it matters, some of information technology we could even call all-time in class, and has earned 1 of TweakTown's highest awards and a hearty recommendation.
Pros:
- All-time Course Factor
- Low Toll
- Multiple Namespaces
- Density
Cons:
- Seq Write
